Dlink DEM-310GT 1-port SFP LX SM Fiber Transceiver
Product Overview
The D-Link DEM-310GT (Model: DEM-310GT) is an enterprise-class 1-port 1000BASE-LX Single-Mode Fiber (SMF) Small Form-factor Pluggable (SFP / mini-GBIC) transceiver module engineered for long-reach Gigabit backbone links, campus inter-building interconnects, and data center connectivity. Designed to operate over standard $9/125\,\mu\text{m}$ single-mode optical fiber cabling using a 1310 nm wavelength, it delivers full-duplex Gigabit data transmission speeds up to 1.25 Gbps over distances reaching up to 10 kilometers. Built with a durable metal housing that reduces Electromagnetic Interference (EMI), the D-Link DEM-310GT features a standard duplex LC optical connector, hot-pluggable architecture for seamless swap-outs without powering down switches, and complete IEEE 802.3z compliance. It is fully compatible with D-Link managed and smart switches (including DGS-1210, DGS-1250, and DGS-1510 series).
